Live in Haslemere and there is some good riding locally, but when we were looking to move I did fancy being closer to Dorking (my wife quickly saw through my lame made up non-MTB justifications to move there). Only thing is a 2 bed cottage in Peaslake was £500k a few years back (2007/8) 😥
My wife travels into East London, 1 hr 40 mins each way (door to door). I often drive (not into London), but it does involve the M25, which is hit and miss.
Not sure the work life balance is that easy to get right, but I would try and avoid having to change to the tube, or drive to the station at the home end. Both add to the travel costs and add time.
